System and method for controlling hard drive data change

摘要

A system for controlling hard drive data change is disclosed which comprises a hard drive having a first volume and a second volume, the first volume for storing data of a first type, the second volume for storing data of a second type, the hard drive being connected to a computer system which restarts the hard drive and an application for running on the computer system for determining whether data of the second type is attempting to change data of the first type to store data of the second type in the second volume, for determining whether data of the second type has been stored in the second volume, and for erasing data of the second type that has been stored in the second volume when the hard drive is restarted by the computer system.

主权项

1. A system for controlling hard drive data change comprising:
a hard drive having a first directory and a second directory, the first directory for storing data of a first type, the second directory for storing data of a second type, the hard drive being connected to a computer system which restarts the hard drive; a mirror hard drive; a file system filter driver for inspecting a file request and for determining whether the file request is targeted to a protected object and for redirecting the file request to the mirror hard drive when the file system filter driver determines that the file request is targeted to the protected object; a file system driver for receiving the file request from the file system filter driver when the file system filter driver determines that the file request is not targeted to the protected object; and an application for running on the computer system for determining whether data of the second type is attempting to change data of the first type to store data of the second type in the second directory, for determining whether data of the second type has been stored in the second directory, and for erasing data of the second type that has been stored in the second directory when the hard drive is restarted by the computer system.
